TQ d?, lwhom t may concern.'

Be it known that we, HARRY H. HirwnLL and Harm?l T. HIPWELL, citizens of the United States, residing at N. S. Pittsburgh, in theeunty of Allegheny, AState of Pennsylvania, have invented a new and useful Pocket Flash-Light, of which the following is a specication. l l

The present invention relates tol improvements in pocket liash lights, and more particularly to that type of light in which a casing carries a battery, andsuch battery is so held therew'ithin as to have one terminal disposed in engagement with an incandescent bulb, there being provided a manually controlled switch for closing .the circuit to light the bulb, one object of' the present invention, being theprovision of means whereby the manually controlled switch may be locked against accidental closure and which may be operated to close only. when depressed, or may be locked in closed position.

A further object of the present invention,

is the provision of a circuit closing means` in combination with a pocket flash light, 1n-

which a spring portion thereof retains the battery seated within the casing, whlle the l upper free terminal constitutes the contact member in combination with a stationary terminal carried byy the` battery.

A still further object of the invention, is the provision of an actuatingmeans which will permit the locking of the free terminal in open or closed positionV or to permit thel actuation thereof manually, the release ca using the terminals to separate and' producing an open circuit.

With the foregoing and other objects in View which will appear as the descriptionA proceeds, the invention resides in' the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed caribe made'within the lscope of what is claimed without departing from the spiritol the invention.

ln the drawings Figure 1 :isA a vertical central sectional view through the complete device, the locking device being in the position it assumes when locking the terminal separated; Fig. 2 is an enlarged detail view showing the switch actuating means in the position vfor locking the terminals closed.- Flg. 3 1s a similar View with the'parts in the position they assume when the terminals'. must be manually operated to close. Fig. 4 isan enlarged detail sectional view showinl the manner of sealing the casingto loc/ the battery therewthin. 5 is a detail rearperspective view of the by the resilient terminal.

Referring to the drawings, the numeral 1 designates the casing, which is made in a flask shape in the 'present instanceyso as t0 be readily accommodated in the hand of the. operator, andso that the same ma be readily inserted within the pocket. he sealed ttora carried lend 2, of the casing is provided with a lamp socket 3 for the reception of the bulb lamp 4, whose terminal 4 is disposed as will presently appear to be engaged by one of the terminals of the battery 9. A hinge' 5 is provided at the open end of the casing 1 to hingedly connect thereto the closure 6, said closure 6 being provided with a clip 7 which coperates with the bead 8 of the casing l to lock the closure in battery seating position. The battery 9 is insertible through the open end so that its resilient terminal 10 will be disposed to engage the terminalfl of the bulb 4 and with the closure 6 sealed,` to be held seated within the, casing 1 so that` a goodl contact may be made between the terminals 10 and 4 Secured to one side of the casingl within the same, by means of the rivet l1 is a plate 12, which has=a long terminal 12 bent to form a resilient member ,and to coperate with onel side of the battery 9 to hold the same over against the opposite side and snugly within the casing 1. The opposite terminal 13 is provided with the right angled switch terminal, 14, which is adapted to bc moved into and out o engagement, being normally held out of engagement due to the resiliency of the terminal 18, of the ixed terminal 10 of the battery 9.

In order to provide a means for actuating the terminal 14, so that the `same may be moved into engagement with the terminal 10', or be locked out of engagement therewith, or locked in engagement therewith, the guide member 15 carries the button 16, and said guide member 15 is slidable upon the ing the terminal 14 relatively' to the terminal 10. When the button 16 is moved upwardly the full length of thevslot 17, the in clined portion lSengages the edge 20, and thus pushes the terminal 14 into engagement with the terminal 10va't which place it is locked by the engagement of the button with the casing 1. 1When the guide portion 15 is disposed adjacent the portion 22 of the battery 9, the same maintains the terminal 14 spaced from the terminal 11, and as the same is rigid at this point, it is impossible by pushing inwardly upon the button 16 to cause the closure of the switch. When the button 16 is in' an intermediate position,

with the guide portion 15 above the upper edge 22 of the battery 9, the terminal 14 is normally out of engagement with the terminal 10, and the button 16 must be de pressed inwardly and there held by the thumb in order-to close the circuit. thus be seen that with the present structure that the button 16 may be locked and the terminal 14 will be held out of engagement with the terminal 10', thus rendering it impossible for an accidental' closure of the Acircuit when the device is in the pocket. It isalso apparent that by the use of the button 16, that the terminals may be closed and held closed manually, and closed and locked in such position as long as desired. v

l/Vh'at is claimed is: A

1. A pocket flash light, including a casing, an electric bulb carried by vone end of the casing, a cell insertible vwithin the 'casing and having two terminals one for engagement 4with the bulb, a combined resilient switch andgcell-holder mounted at one side within the casing for engagement with the cell, the switch being disposed adjacent to the other terminal of the cell, and means operable from the exterior of the casing for operatingthe switch to engage the re- L l slidable within.u said slot and having means spective terminal.

2. A pocket ash light, including alcasing,

. an electric bulb carried byv one end of the casing, a cell insertible within the casing.

and having two terminals, one for engagementwith the bulb, a resilient strip of metal secured intermediate of its ends to the inner, side of the casing, one' portion thereof being bowed to constitute a cellholder andv 'the other portion being free for disposition adjacent the other terminal ofl the cell, and

It will means forfactuating the free portion of the strip to engagethe respective terminal of the cell. l

A pocket flash light, including a casing, a contactstrip secured to the inner side of the casing to coperate with one terminal of the cell inserted Within the casing, a slidable doublecam member mounted upon the contact strip and .operable eXteriorly of the casing, the cam member being coperable with the cell to lock the contact strip separated from the respective terminal and cooperating with the casing to lock the contact strip in contact with the terminal, and when in an intermediate position, allowing the contact strip to be out of contact with the terminal ofthe cell for depression manually. t e f 4. A pocket flash light, including a casing, a contact member carried thereby for coperation with one terminal of a cell inmeans for said contact member arranged when in one position to lock the contact member in engagement with said terminal, when at another position to allow the con- .serted within the casing, and actuating tact member to move out of engagement with' saidterminal and to be pressed into engagement therewith, and when in another position to lock the contact member out of engagement with the said terminal.

A pocket flash light, including a cas- Ving, a contact strip secured thereto to coperate with one terminal of a cell inserted Within the casing, and an actuating member slidable along the -contact'strip and the casing, the actuating member and casing having coperable means whereby when theA actuating member is 'in one position it will hold the contact strip in .engagement with said terminal, when the contact member is at another position it will allowthe'contact y strip to move out of engagement '.with said terminal and permit the actuating member to be pressed for moving the contact strip into engagement with saidjterminal, and when the actuating member is i'n vanother positionv it will lock-the contact strip out'of engagement with said terminal.

6. A pocket flash lightincluding a casing having aslot therein, a. contact strip secured within the casing, and arranged to cooperate With the terminal of a cell inserted within the casing, and a double cam member slidably engaging the contact strip.
